BEE, OF CLEVELAND, OHIO, ASSIGNOR 1'0 I'HEEATON ELANUFACTURING COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIOSEALING GASKET FOR NECK AND CLOSURE STRUCTURES Application filedFebruary 1, 1929. Serial No. 336,:52.

This invention relates to improvements in gasoline tank. Said bodymember may be sealing gaskets for neck and closure strucan integral partof said receptacle or a septures, and more particularly, for neck andclosure structures. of the bayonet-joint type. These structures areused, for example, with the radiators andtbe gasoline tanks ofautomobiles and eachincludes a tubular neck hav ing one end adapted tobe secured to the radiator or gasoline tank around the ening therein anda closure adapted to be etachably connected to the other end of theneck, the sealing gasket being interposed between the closure and theneck.

The general object of the present invention is the provision of animproved sealing gasket for neck and closure structures of the characterdescribed, said gasket being of the usual annular form but instead ofbeing a solid member is a, hollow member filled with com- 5 pressed airor the like, said gasket being of simple and inexpensive constructionand having especially effective sealing portions for line engagement orcontact with both the neck and the closure of the neck and closurestruc- 95 ture.

Further ob'ects of the invention are in part obvious and in part willappear more in detail hereinafter.

In the accompanying drawin Fig. 1 is a an central vertical sectionalview 0 one form of neck and closure structure having my improved sealinggasket, the view throu h the closure'being on the line 1--1, Fig. 2; ig.2 is a bottom lan view of the closure of the structure; Fig. 3 is a topplan view of the neck of the structure; Fig. 4 is a central verticalsectional view of said neck on the line 4-4, 3; and Fig. 5 is a sideview of the resent improved sealing gasket the gasket 10 eing partly insection and partly in elevation.

In the present embodiment of the invention, I have illustrated a neckand closure structure of the 'form shown in m Patent No. 1,593,847, ofJuly 27, 1926, to w ich patent reference may be bad, if desired. Theneck of the structure here illustrated includes a tubular body member 1ada ted to be positioned about the opening 2 o a re- 60 ceptacle 3, suchas an automobile radiator or arate member suitably secured thereto, thelatter arrangement being here shown with said body member provided witha laterally or otherwise suitabl secured to the receptacle 3. Said bodymember is provided at its upper end with an inwardly extendingtransverse wall b which terminates in a depending flange 6. At twodiametrically opposed points, portions of wall 5 and flange 6 are cutaway to provide two opposed passageways 7 through which are adapted tobe passed the locking fingers of the closure of the structure, as willlater appear. The cutting away of portions ofsaid wall and said flangeprovides two depending flange portions 6 each of substantiallysemi-circular form and the lower edges of said flange portions areinclined to provide cam surfaces 8 along which ride the closure lockingfingers in efiecting detachable connection of the closure to the neck.To limit rotary movement of said closure locking fingers up along saidcam surfaces, each of the flange portions 6 is provided with a dependingsto projection 9 adjacent the inner end or t e high point of its camsurface, and adjacent these stop projections each cam surface isprovided with a dwell 10, in which dwells the closure locking fingersare adapted to seat when the closure is completely connected to theneck, all as will later appear.

The closure of the structure includes a body member having a dome-shapedtop portion 15 and a depending cylindrical skirt portion 16 having adiameter slightly larger than that of the tubular neck body member 1, asclearly indicated in Fig. 1. Crimped or otherwise suitably secured tothe closure body member at the junction of the top and skirt portionsthereof is the edge portion 17 of a transverse disc 18 having a centralcavity within which is crimped or otherwise suitably secured thesubstantially circular base portion 20 of the closure locking member.Said locking member also includes two diametrically opposed resilientlocking fingers 21 extending downwardly and outwardly extending baseflange 4 adapted to be welded from the base portion 20 thereof, asclearly shown in Fig. 1.

The closure is detachably connected to the neck by passing the lockingfingers. 21 thereof downwardly through the neck passageways 7, theclosure being then turned in a clockwise direction which causes theclosure locking fingers to ride up the neck cam surfaces 8 until theyreach the dwells 10 therein, further rotary movement in this directionof the closure locking fingers being prevented by the stop projections9. To remove the closure it is only necessary to turn it in the reversedirection, whereupon the closure locking fingers leave the dwells 10,ride down the cam surfaces 8 until they reach the passageways 7, afterwhich the closure can be readily lifted from the neck, all as will bereadily understood.

For sealing purposes, a resilient gasket is usual y interposed betweenthe closure and the neck of such a structure, said gasket lying betweenand engaging the top transverse wall 5 of the neck and the lowermarginal surface of the transverse disc 18 of the closure. These gasketsare usually of cork, rubber or other material having the desired amountof resiliency but which are more or less rapidly deteriorated ifsubjected to certain liquids, such as the anti-freezing solutions putinto automobile radiators in the winter.

The present improved sealing gasket is of extremely simple construction,with the necessary resiliency to make its sealing portions especiallyeffective but made of metal or some other material which is notdeteriorated if subjected to the anti-freezing solutions abovementioned, one material suitable for the purpose being spring brass.

Instead of being of the usual solid form, said gasket is hollow and isfilled with compressed air or the like, which gives the gasket plenty ofresiliency but without sacrifice of strength or of durability. Thegasket is of the usu. l annular form in plan view but may be ofdifferent forms in cross section, so long as it possesses two edge orangular sealing portions for substantially line contact or engagementwith both the closure and the neck.

In the present embodiment of the invention, the gasket is ofdiamond-shape in cross section and is made up of two members, similar inconstruction, an annular top member 25 of inverted substantiallyV-shaped cross section and an annular bottom member 26 of substantiallyV-shaped cross section. Said members have their inner and outer edgeportions suitably interconnected by air-tight joints, and for thepurpose of such connection, each of said members is provided at itsedges with laterally extending annular flanges, the flanges of onemember, such as the flanges 28 of the bottom member 26, being bent orcrimped around the flanges 29 of the upper member, which flanges arepreferably of less width, as shown.

The upper gasket member 25 is therefore provided with an annular ridge31 of angular cross section for substantially line contact or engagementwith the cross wall 18 of the closure and the lower gasket member 26 isprovided with a similar annular ridge 32 of angular cross section forsubstantially line contact or engagement with the cross wall 5 of theneck, as indicated in Fig. 1. Of course, the position of the gasketmight be reversed to make gasket member 26 the upper member and gasketmember 25 the lower one. In this case, the gasket ridge 32 will engagethe closure and gasket ridge 31 will engage the neck, as will be readilyunderstood.

The annular chamber 35 of the asket is filled with compressed air or thelike which gives the gasket suflicient resiliency to enable its sealingridges 31, 32 to engage the closure and the neck with the desiredpressure to effect tight seals, even though the closure locking lingers21 are made quite resilient to enable the closure to be very easilyconnected to and disconnected from the neck.

I claim:
